Your whole position sounds like that of someone who is trying to justify their decision not to advance their own education. I don't know if that's the case or not, and I really couldn't care less. However,
if that is the case, you should understand that while making up trends about a field you don't work in might make you feel better about your decision, you really do lose credibility when you insist that you have a better understanding of those trends than the people whose paychecks depend on them. The fact that you make more money as an RN than APN's in your hospital is highly localized and has to do with state and local politics, not the greater trends in healthcare economics.
It's the same dribble that's been said for over a decade. The AAMC is also a bit biased and has been pushing for more residency and med school spots for a long time, well before the boomer retirement crisis.
Well, the "dribble" that you refer to has come to pass. I'm not sure what numbers you are looking at, but there is currently - and has been for some time - a real shortage of physicians, both primary care and specialist. Naturally, the shortage is more acute in some locales, and non-existent in others. We are talking about national trends. This most recent report simply predicts that the existing trend will accelerate.
The reason the AAMC has pushed for more seats is because they've known for decades that not enough physicians were being trained, and since they aren't puppets of the AMA like the ACGME is, they've tried to match seats to actual projected need. However, in their infinite and altruistic wisdom, the AMA (through the ACGME) has intentionally trained fewer physicians than they knew would be needed, and they did it in order to create a shortage and artificially inflate demand and compensation for doctors. This whole thing is not only real, but it's actually by design. What the AMA didn't count on is that they'd shoot themselves in the foot by creating as much demand for APN's as they did MD's.
It is my understanding that you practice in a lower resource non-urban/metro hospital. I'm happy that you are happy where you are working. That being said most new APRNs/PAs/Docs don't want to work in a rural area... hence said shortage.
While I personally choose to live in the sticks, my hospital is actually within an easy commute of one of the most desirable and fastest growing urban areas in the country, in one of the fastest growing states in the country. A city that has seen home values literally double in the past 5 years. In fact, two of my 5 colleagues commute daily from there.
